64GB DDR4 ECC Registered RDIMM

This 64GB DDR4 3200 module is built for servers and workstations that require ECC registered memory. It operates at 1.2V with a CL22 latency and a 2Rx4 rank configuration. The 288-pin RDIMM fits standard DDR4 server slots and matches the specifications of Hynix HMAA8GR7AJR4N-XN and HMAA8GR7CJR4N-XN parts. It is not compatible with standard desktop computers or unbuffered memory configurations.

Installation and compatibility

Installation follows standard DDR4 RDIMM procedures, but the module must be paired with identical capacity, speed and registered ECC modules for stable operation. Mixing with unbuffered or non-ECC DIMMs will prevent the system from booting. Verify that your platform supports registered ECC memory before purchase, as consumer motherboards typically do not. No heat spreader is present, so airflow across the DIMM is recommended.

Capacity and headroom

The single 64GB module provides substantial memory capacity for virtualisation, database workloads and large-file processing. Systems populated with multiple modules can scale to high total capacities within the platform's supported limits. Performance is governed by the DDR4 3200 JEDEC standard; the module does not support overclocking or XMP profiles. Headroom is determined by the number of available DIMM slots and the memory controller's maximum supported density.

Questions sur cet article

How can I confirm the 64GB DDR4 3200 module is running at PC4-25600 with CL22 after installation?

Check the BIOS or UEFI memory information screen; it should report 3200 MT/s, 1.2 V operation, CL22 timings and ECC Registered status for each installed DIMM.

What ships with the OWC 64GB DDR4 3200 ECC RDIMM and what must I source separately?

The box contains the single 288-pin 2Rx4 module only; no heat spreader, tools or additional DIMMs are included.

Which capacity and rank configuration should I select for a server that requires 64 GB per DIMM slot?

Choose this 64 GB 2Rx4 Registered ECC DDR4 3200 module; it matches the Hynix HMAA8GR7AJR4N-XN and HMAA8GR7CJR4N-XN specifications exactly.
